Boilers & Heaters

SOT offers Fully Automatic Coil Type Boilers to generate instant steam. It consists of Double Helical Coil, made out of Carbon Steel. Conventional design of three pass is used effectively to get best heat transfer efficiency. The pump injects water in the helical coil & Burner fires vertically downward in the chamber made from the Coil. After complete Combustion, the gases pass through suitably designed passage in between two coils & then through third pass of coil & inner shell. Heat is recovered by Air passing through inner & outer shells, thus providing preheated air for combustion. This improves upon Combustion efficiency. Aluminum radiator placed between the shells eliminates the heat loss to atmosphere, thus eliminating the external insulation.

As per standard practice, we offer water preheater with the boiler. The same is placed in the exit steam of flue gas. Thus water fed to the boiler is also preheated for higher Thermal efficiency. All boilers are backed by proven track record of SOT Fully Automatic Pressure Jet Burners. SOT Boilers are available in Gas &/or Light/Heavy Fuel oils. However, boilers below 300 kg/hr are not recommended with Furnace Oil as fuel. Boilers are mounted on skid platform, prewired and assembled, ready to install. The unit shall be commissioned, immediately after Fuel line & Power supply is connected to the system.

We are the manufacturer of electric water heaters which are used as fuel to heat water or steam and circulate the hot water through pipes. The Electric Water Heater, offered by us, is used to heat and/or produce hot water for personal or industrial use.

In recent times, thermic fluid heaters have found wide application for indirect process heating. Instead of water, petroleum based fluids are the heat transfer medium, and provide constantly maintainable temperatures for the user equipment. The combustion system comprises of a fixed grate with mechanical draft arrangements.

The advantages of these are:
- Closed cycle operation with minimum losses as compared to steam boilers.
- Non-Pressurized system operation even for temperatures around 250 Deg. C as against 40 kg/cm2 steam pressure requirement in a similar steam system.
- Automatic control settings, which offer operational flexibility.
- Good thermal efficiencies as losses due to blow down, condensate drain and flash steam do not exist in a thermic fluid heater system.
